//7 vc-v? for w iiy Patented June 30, 1931 UNITED STATES PATENT OFFICE iADOLPH G. KUPETZ, OF NEW ROCHELLE, NEW YORK, ASSIGNOR TO UNDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE TYPEWRITING MACHINE Application .filed September 25, 1924. Serial No. 739,807.

This invention relates to typewriting machines, and mainly to means for registering the number of toll items written upon a bill or a succession of bills for telephone service and the like.

According to one form of the invention, a cam-finger is effective during the return of the carriage to engage a cam-piece for actuating a lever pivoted to the front rail upon which the carriage travels, the lever being connected through suitable linkage to a register or counter, which may be of the type of the well-known Veeder cyclometer. The parts are so related that the operation is limited to a certain typing zone. The counter does not operate until the amounts column of an inserted bill has been typed upon, and the carriage returned. This forms a feature of the present invention. The carriage may, if necessary, be moved back to a position for writing in the date column or name of exchange at any stage of the typing operation, prior to making an entry in the amounts column without causing the register to operate.

Another feature of the invention is the provision of a novel form of linkage for transmitting motion to the counter. The counter may be attached to the left-hand side of the main frame of the machine, and the operating crank ofthe counter may carry a resilient arm which lies in the path of movement of the escapement rack-arm and of an obstruction adjustably secured to the escapement rack, so that, as the carriage moves back and forth, the arm and the obstruction alternately strike the resilient arm which thereupon causes the register to operate. Use of the resilient armto operate the register avoids the necessity of providing for fine adjustments relatively to the co-operating parts of the carriage, and forms another feature of the invention. A novel form of obstructionelement, such that the same may be readily adjusted and securely clamped in position upon the escapement rack of the machine, embodies another feature of the invention. Y

A further feature is the provision of a simplified form of bracket for mounting the register upon the main frame of the machine by means of a singlescrew, the bracket being securely held against movement both laterally and longitudinally of the frame.

Other features and advantages will hereinafter appear. y

The mechanism forming the present invention is illustrated in connection with an Underwood standard typewriting machine, which includes a main frame 10 having a right-hand portion or framework 11. A carriage 12 is mounted upon the usual carriage rails, the front rail or margin-stop rack-bar being indicated by the reference numeral 13, and a thumb-piece 14 of the carriage provides means whereby the latter may be shifted upon its rails toward the right of the machine. The margln-stop rack-bar 13 and a margin-stop-carrying rod 15 extends across the machine in parallelism,

the rod providing a mounting for the usual margin-stop 16 which is settable upon the rack-bar and arrests the. travel of the carriage in its extreme right-hand position, or, in other words, for typing in the first column of ;a bill. A platen cylinder 17 is mounted in the carriage, and a line-space lever is indicated in broken lines at 18. In connection with the present invention a bar 19 is substituted for the conventional carriage-stop release lever, and may be rigidly secured to the cross-rail 23 of the carriage by screws 21 and position.

5 secured upon the under side of the shelf 55, as shown in Figure 5.

22. An end portion 24: of bar 19 is bent to provide a linger 25, which is engageable with the carriage-stop 16 to limit the movement of the carriage to the right or line-starting A. cam-finger 20 may be provided by bending the bar 19 laterally and upwardly at the end portion thereof opposite to the finger 2 A lever 27 is pivoted at 28 upon the inner side of the margin-stop rack-bar 1 so as to provide a pair of arms 29 and 30, the arm 29 tern'iinating in a right-angular bend 31 which arranged to underlie the lower edge 32, and thereby act as a limiting stop or resting ledge for an extension-piece 33 pivoted at 3i upon the lever 27. The extension-piece 33 includes a turned-over upper edge to form an upper face 35 and an under face 35'. A shield-plate 27, shown in Figure 5, overlies the above-dcscribed mechanism, and is secured :in position by a screw 28 passing through the cross-brace 2f of the frame it) of the machine. The arm 30 of the lever 27 has a perforation adjacent its free end, as indicated at 36, to receive the upper end of a depending rod 37, the lower end of the rod being connected to registering mech anism, which will noW be described.

Upon the right-hand portion or frame work 11 of the machine there is positioned a bracket 38, which includes a leg 39 fastened to the frame by means of a screw s0 and a nut 41.. A shelf e12 forms the upper portion of the bracket 38 and overlies a portion of the framework 11. An outstanding stud (1'3,

rt) 7 engages a perforation in the framework 11 andv holds the snelf in position. A register or cyclometer counter a l is secured upon the shelf 1-2 by any suitable means, such as screws 4:5, and includes a crank-arm 46 for imparting motion to a shaft 47 to cause aseries of register-wheels, indicated at 48, to index. Adjacent the lower end of the rod 37 and upon the inner side of the framework 11, there is provided a boss 49, and a bell-crank lever 50 pivotally secured thereto by means of a cap-scrc 51 passing through a perforation in the lever and threaded into the boss. One arm 52 of the belbcrank lever 50 is directed upwardly within the machine and has its end perforated as at 53 to provide means for attaching one end of a tension spring 54;, the other end of which is anchored to the framework 11 through the medium of a stud The arm 56 of the lever 50 extends forwardly and has its free end connected by a toggle-joint 57 to one end of a V -shaped link 58, the other end of the latter being pivotally connected at 59 to the outer end of the crank-arm 46 of the register 4st. The lower end of the rod 37 is bent to form a loop 60, which is arranged to engage around a stud 61 carried upon an offset portion (32 of the lever 50.

Reference letter 6 represents a billing form, such as commonly used for making out charges for telephone service, the form having been run around the platen 17 and into position to be typed upon. The billing form may be ruled, as illustrated in Figure 1, to include a date cohunn (Z, a. name of exchange column c, an amount of charge column (1 and a code column 0.

The operation of the device as follows: Assuming a form 7) to be fed into proper position uponthe platen, and the carriage shifted to bring the date column (Z to the printing field, the printing kc of the machine may be operated to print the date, whereupon the carriage is shifted. to the column a and the name of the telephone exchange written therein. The carriage is then shifted to the amounts column (I! and the charge for service, sucl as .05, written therein. If a code letter is used the carriage is shifted to the column 0 am. an np iropriate character typed. therein. During the shifting of the carriage to the left, the cam finger 20 has been traveling toward the extension piece 33, and, when the carriage has moved sutliciently to the left, the finger engages the under face 35 to raise the extension piece about its pivot and thereby permit the cam-linger to pass to the left of the machine (see Figure 2). The column (I/ is so positioned with relation to the cam-linger that, as the amount of charge typed, the cam-finger passes from beneath the under face 35, thus permitting the extension-piece 33 to drop back to normal position, as indicated in Figures 1 and 3. Now, upon return of the carriage to the right, the cami'inger engages the upper face 35 and rides upon the same, thereby causing the lever 27 to rock about its pivot to lift the rod 2137 against the action of the spring 54, and thus cause the register 44- to index a count (see Figures 3 and It will be noted that the carriage may be returned during any stage of the typing operation prior to print ing in the a column, to bring either the I] or c column to the printing field for writing the date or exchange name, in the event that either of these entries had been omitted in the first instance.

Variations may be resorted to within the scope of the invention, and portions of the in'iprovements may be used without others.

Having thus described my invention, I claim 1. In a register-operating mechanism for typewriter-carriage, a counter, a lever piw oted intermediate its ends, and having an end portion thereof provided with a pivoted extension, operating connectitms between the other end of the lever and the counter, and an obstruction element for use upon the carriage and effective during letter-feed movement of the carriage to pass beneath said 0::- tension, and upon return movement of the carriage to ride upon said extension to actuate said lever and thereby cause the counter to index.
